Serial No. 698,180.

To all whom it may concern:

Be it known that 1, James W. Mosnnn, a citizen of the United States,residing at Berkeley, in the county of Alameda and State of California,have invented new and useful. Improvements in Road-Planers, of which thefollowing is a specification.-

The present invention relates to improvements in road planers.

Roads having an oiled surface, now commonly used, have a tendency towear into a form having transverse ridges.

The object of the presentinvention is to provide a simple, convenientlyoperated, and ejtlj'e'ctive device for removing these ridges, andrendering the surface of the road again plane.

In the accompanying drawing, Figure 1 is a plan view of my improved roadplane; Fig. 2 is a longitudinal vertical section thereof; Fig. 3 is aperspective view of one of the cutters.

Referring to the drawing, 1 indicates two parallel skids spaced apart asuitable dis tance and ot' a rectangular cross section, each havingupwardly beveled ends 2, and shod in the central portion with a steelshoe Said skids are connected by transverse beams l at the top, and bybraces 5 crossing each other obliquely. T o the inn-er verticz 1. sidesof the skids at each end are connected hooks G, to which can be attachedthe d aft harness ot' a. horse or horses.

Each skid formed with hearings T for crank-shaped holders 8, to thecentral portion of which cutters 9 are attached by loops 11 havingthreaded stems 12 on the outer ends of which passing through retainerbars 13, on the other side of the holder from the cutters, are screwednuts 141:. The side members 15 of the holders are extended to formhandles 16 for changing the direction oi? said holder and on saidextensions are formed fulcrum posts 17, on the ends of which are pivotedlevers 18, one end of each lever 3eing pressed outwardly by a spring 19,and the other end engaging an end of a pin 20 passing through a hole insaid member 13,

enter any one of a. circular series of holes 21 formed in the skid. Bythis means the cutter holders can be set at any desired angle relativelyto the skid. I provide two cutter holders so that the cutters ot thesecond holder may operate upon parts of the road which pass between thecutters oi. the first: holder.

lilach cutter is formed with one end 2:2 pointed, andwith a scrapingedge 23 at the other end, and when the apparatus is drawn over the road,the pointed ends 22 (It the cutters, which extend below the steel shoes,penetrate the high places or ridges in the road, but do not touch thedepre .d portions thereof, and thus thoroughly cut up said ridges. lVhen a section of road to be treated has been traversed by the planer inone direction, the cutter holders are turnei'l in. their bearings, sothat the edges 28 of the cutters are new lowermost, and act as scrapersto push or scrape the earth loosened from the ridges into thedepressions.

.l claim A road planer comprising a frame having side pieces, a ttshapedholder pivoted at its ends in said side pieces, a series of cutterssecured to the middle portion of said holder, one end of each cutterbeing formed with a sharp point and the other with a scraping edge, saidside pieces each having therein two series of holes equidistant from thepivot of the holder in. said side piece, one series being in front andthe other behind the pivot, a pin adapted to enter any one oi. saidholes in a side piece, and arrangeiil to lock the holder to said piecein any one ot a series of positions thereon so that said cuttors are introut of or behind said pivots.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
